BACKGROUND

Augmented reality (AR) is a new technology for realizing content convergence between real world information and virtual world information by simulating and superimposing a virtual object onto a real-world environment, which may enhance the visual perception of a user.

At present, in a scene based on the AR technology, content delivery and representation are realized only by a virtual object created in an AR space.

However, such a manner of content delivery merely by means of the virtual object in the AR space leads to the virtual object not matching the real-world environment of a user, resulting in distorted visual representation of the AR space and thus affecting the effect of visual display. Moreover, in a scene involving multi-user interaction, the experience of interaction among a plurality of users is also reduced.

DETAILED DESCRIPTION

In order to make objects, technical details and advantages of the embodiments of the present disclosure apparent, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the present disclosure. Apparently, the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the described embodiments herein, those skilled in the art can acquire other embodiment(s), without any inventive work, which should be within the scope of the present disclosure.

Firstly, terms involved in the embodiments of the present disclosure are explained below.

-   -   1) An augmented reality is called AR for short. The augmented         reality, which may also be referred to as extended reality,         involves simulating a real object information which is unlikely         to be played in a spatial scope of the real world and         superimposing it onto an image corresponding to the real-world         environment, allowing people to perceive through visual         perception and thus to have a sensual experience beyond reality.         A picture and space displayed after the superimposing of the         virtual object onto the real-world environment is called an AR         space. The AR space may show not only the image information of         the real-world environment, but also the image information of         the virtual object superimposed onto the real-world environment.         Thus, users may see the real-world environment and the virtual         object simultaneously in the AR space.     -   2) A terminal device, also referred to as a terminal or a user         device, is a device for providing voice and/or data connectivity         to users, for example, a hand-held device or a vehicle-mounted         device with a wireless connection function. The terminal device         may also be a device for detecting data, such as a sensor. The         terminal device may also be a smart device, such as a smart home         device deployed in a room, and a wearable device. Common         terminal devices, for example, include: an air quality         monitoring sensor, a temperature sensor, a smoke sensor, a         mobile phone, a tablet computer, a notebook computer, a palm         computer, a mobile internet device (MID), and a wearable device,         where the wearable device, for example, include: a smart watch,         a smart bracelet, a pedometer, etc. The terminal devices are         existing and future possible terminal devices of wireless         communication or terminal devices of wire communication.     -   3) The term “a plurality of” refers to two or more than two, and         other quantifiers are similar to this term. The term “and/or”         describes associations between associated objects and indicates         three types of relationships. For example, A and/or B may         indicate three situations: A exists alone, A and B exist         simultaneously, or B exists alone. The character “/” generally         indicates that the associated objects are in an “or”         relationship.     -   4) The term “corresponding to” may refer to an association         relationship or a binding relationship. A corresponding to B         refers to that A is in an association relationship or a binding         relationship with B.

It needs to be noted that the terms involved in the embodiments of the present disclosure may refer to one another, which will not be described redundantly.

FIG. 1A is a schematic diagram of an application scene based on AR according to embodiments of the present disclosure. Referring to FIG. 1A, in the scene provided in this embodiment, a user A collects image information of surrounding environment through an application (APP) running on a terminal device and superimposes a virtual object and information onto an image of a real-world environment. Thus, various applications based on AR, such as an AR game and an AR map, may be realized.

On the basis of FIG. 1A, FIG. 1B is a schematic diagram of a multi-user interaction application scene based on AR according to embodiments of the present disclosure. Referring to FIG. 1B, in the scene provided in this embodiment, user A and user B are in communication connection with a server through terminal devices, respectively, and interact with data through processing and forwarding by the server, allowing for cross-scale AR interaction in different environments. The terminal device may be, for example, a smart phone. The user may run a preset APP on the terminal device to realize, for example, a multi-user interactive game based on AR.

FIG. 2 is a schematic diagram illustrating a method for AR interactive display in the prior art. Referring to the schematic diagram of the application scene shown in FIG. 1B and the schematic diagram shown in FIG. 2 , in a multi-user interaction scene based on AR in the prior art, content delivery and representation are performed among a plurality of users only by means of a virtual object created in an AR space, thereby realizing interaction among the plurality of users. For example, as shown in FIG. 2 , there is a virtual football in an AR space displayed by a first terminal device, and there is also a virtual football in an AR space displayed by a second terminal device. When user A inputs an operation instruction to cause the virtual football displayed in the AR space corresponding to the first terminal device to move, the virtual football displayed in the AR space corresponding to the second terminal device may also move synchronously, thereby realizing interaction between user A and user B.

However, when realizing the above-mentioned multi-user interaction based on AR in the prior art, interactive content is represented only by means of the virtual object in the AR space without considering a matching relationship between the real-world environment and the virtual object in the AR space. This is because, unlike an offline single-user AR application scene, in the multi-user interaction scene based on AR, due to different real-world environments of users, it is impossible to set a unified scene scale, so that a virtual object can be displayed in the AR spaces of a plurality of terminal devices on the unified scale. As shown in FIG. 2 , the size and moving distance of the virtual football displayed in the AR space corresponding to the second terminal device are determined with reference to the size and moving distance of the virtual football displayed in the AR space corresponding to the first terminal device. However, the second terminal device and the first terminal device are placed in difference environments. Specifically, the first terminal device is placed in a room with narrow space, and the virtual football moves in a narrow area at a corner. The second terminal device is placed outdoors with open space, and the virtual football may be displayed in a larger size and move in a larger range. Thus, the size and moving distance of the virtual football displayed in the AR space corresponding to the first terminal device do not match the real-world environment in the AR space corresponding to the second terminal device, resulting in problems that the size and movement of the virtual football in the AR space corresponding to the second terminal device being unable to match an open environment visually, which affects the visual display effect and reduce the experience of AR interaction between users.

Embodiments of the present disclosure provides a method for augmented reality interactive display to solve the problems described above.

FIG. 3 is a first flowchart of a method for augmented reality interactive display according to embodiments of the present disclosure. The method provided in this embodiment may be applied to a first terminal device. The method for augmented reality interactive display includes steps described below.

S101: acquiring scene scale information, in which the scene scale information is used for characterizing dimension information of a real-world environment represented by an augmented reality space of a first client.

Exemplarily, the first terminal device is, for example, a smart phone. In a possible implementation, a first client for realizing an interaction function based on AR runs on the first terminal device. More specifically, the first client is, for example, an APP based on AR running on the smart phone, or an APP based on AR running on smart glasses. Further, the first client acquires the scene scale information of the real-world environment by means of the first terminal device, and displays the augmented reality space through a human-machine interaction interface of the first terminal device, allowing users to see the augmented reality space through the first terminal device and then to visually perceive the real-world environment and a virtual object superimposed onto the real-world environment in the augmented reality space. Thus, a plurality of applications based on AR may be realized.

In another possible implementation, a first client used for realizing a multi-user interaction function based on AR, for example, a multi-user AR game client, runs on the first terminal device. The first client may realize interaction based on AR with one or more second clients by communicating with a server. More specifically, the first client is, for example, an APP based on AR running on the smart phone, or an APP based on AR running on smart glasses. In this application scene, the first terminal device and a second terminal device acquire corresponding scene scale information, respectively, and display the augmented reality space through respective human-machine interaction interfaces thereof. Thus, applications based on AR with the multi-user interaction function may be realized.

The scene scale information is used for describing the information of dimensions of the real-world environment represented by the augmented reality space. Exemplarily, when the first terminal device is placed in a large-scale environment (e.g., the real-world environment where the first terminal device is placed is a playground), the real-world environment displayed in the augmented reality space of the first client has large dimensions accordingly. For example, the playground is 100 m long and 50 m wide. In this case, the scene scale information includes the information of a length of 100 m and a width of 50 m. When the first terminal device is placed in a small-scale environment (e.g., the real-world environment where the first terminal device is placed is a room), the real-world environment displayed in the augmented reality space of the first client has small dimensions accordingly. For example, the floor of the room is 6 m long and 3 m wide. Correspondingly, the scene scale information includes the information of a length of 6 m and a width of 3 m. It needs to be noted that the scene scale information may be implemented by a variety of ways. Apart from the above-mentioned examples, the scene scale information may also be implemented by using various types of dimension information such as a volume, a projection area and a diagonal length of the real-world environment, which will not be described here redundantly.

The scene scale information may be acquired by a method of, for example, collecting image information of the real-world environment where the first terminal device is placed by using an image collecting unit, more specifically, a camera, which is provided on the first terminal device, and acquiring the scene scale information from the image information. The image information may be a picture or a video.

More specifically, in a possible implementation, a method of acquiring the scene scale information includes: acquiring video image information of the real-world environment, and determining the scene scale information by a preset simultaneous localization and mapping (SLAM) algorithm according to the video image information. The SLAM algorithm is a method for acquiring position information according to image features. According to the SLAM algorithm, a plurality of image frames of video images of the real-world environment acquired by the image collecting unit such as the camera are processed so that the scene scale information capable of characterizing the dimension information of the real-world environment may be acquired.

The scene scale information may also be acquired by reading, according to an instruction or configuration information input by a user, the scene scale information which is preset on the first terminal device and corresponds to the instruction or the configuration information input by the user. There is no particular limitation on this here.

S102: determining display scale information of a virtual object according to the scene scale information and reference scale information, in which the reference scale information is used for characterizing dimension information of the virtual object in a reference environment, and the display scale information is used for characterizing dimension information of the virtual object in the augmented reality space of the first client.

Exemplarily, the virtual object may be a digital model preset in the first client. The virtual object has different dimension information in different environments. When the virtual object is in a preset reference environment, the dimension information thereof is the reference scale information. FIG. 4 is a schematic diagram illustrating reference scale information of a virtual object according to embodiments of the present disclosure. Referring to FIG. 4 , the virtual object is a virtual football. When the virtual football is in a reference environment of which the length and the width are both 1 m, the diameter of the virtual football is 0.3 m. Exemplarily, the reference scale information is capable of characterizing the dimension information of 0.3 m of the virtual object. In the case of taking the virtual object and the reference environment as a whole, the dimension information of 1 m of the reference environment may also be used as the reference scale information. This may be determined according to specific situations here. Further, the reference scale information may be data preset in the first client, in which the reference scale information of the virtual object may be modified according to instructions input by a user, in order to allow the virtual object to represent different information contents. Exemplarily, in the case of multi-user interaction, the reference scale information of the virtual object may be determined based on interaction information received on other terminals.

Further, the virtual object may be displayed in the augmented reality space with different dimensions, and the information describing the dimensions of the virtual object displayed in the augmented reality space is display dimension information. To realize matching of the virtual object with the real-world environment, the scene scale information is directly proportional to the display dimension information. That is, the greater the scale of the real-world environment, the larger the display dimensions of the virtual object. Therefore, the display scale information of the virtual object may be determined by scaling up or scaling down the reference scale information according to the scene scale information.

S103: displaying the virtual object in the augmented reality space of the first client according to the display scale information.

FIG. 5 is a schematic diagram illustrating display scale information of a virtual object according to embodiments of the present disclosure. Referring to FIG. 5 , the virtual object is a virtual football. The reference scale information of the virtual football is 0.3 m, and the display scale information is determined to be 0.6 m after the reference scale information is scaled up according to the scene scale information. That is, the virtual object is displayed in the augmented reality space of the first client with the dimension of 0.6 m. When a user watches the virtual football in the augmented reality space through the first client, the perceived dimension of the virtual football is 0.6 m. The virtual object is displayed in the augmented reality space according to the display scale information so that the virtual object may match the real-world environment in the augmented reality space. Thus, the purpose of improving the visual representation effect of the virtual object is achieved.

The method for augmented reality interactive display provided in this embodiment includes: acquiring the scene scale information, in which the scene scale information is used for characterizing the dimension information of the real-world environment represented by the augmented reality space of the first client; determining the display scale information of the virtual object according to the scene scale information and the reference scale information, in which the reference scale information is used for characterizing the dimension information of the virtual object in the reference environment, and the display scale information is used for characterizing the dimension information of the virtual object in the augmented reality space of the first client; and displaying the virtual object in the augmented reality space of the first client according to the display scale information. Since the display scale information of the virtual object is adjusted according to the scene scale information, the display scale information of the virtual object in the augmented reality space may match the scene scale information. Thus, the virtual object may be displayed in the augmented reality space on a more appropriate scale and be closer to the real-world environment, resulting in making the virtual object closer to the real-world environment, improving the visual display effect of the virtual object, and enhancing the experience of interaction among a plurality of users.

FIG. 6 is a second flowchart of a method for augmented reality interactive display according to embodiments of the present disclosure. This embodiment of the present disclosure provides further details of step S102 on the basis of the embodiment shown in FIG. 3 , in which the reference scale information includes reference environment scale information and reference object scale information. The method for augmented reality interactive display includes steps described below.

S201: acquiring the scene scale information, in which the scene scale information is used for characterizing the dimension information of the real-world environment represented by the augmented reality space of the first client.

S202: determining a scale adjustment coefficient according to a relationship between the reference environment scale information and the scene scale information.

Exemplarily, the reference environment scale information is used for describing the information of dimensions of the reference environment, and the reference object scale information is used for characterizing reference dimension information of the virtual object in the reference environment. The dimensions of the virtual object in the reference environment are different from the dimensions of the virtual object displayed in the augmented reality space, and the latter needs to be adjusted according to the dimensions of the real-world environment on the basis of the former such that the virtual object matches the real-world environment. The scale adjustment coefficient is a parameter used for adjusting the dimensions of the virtual object in the reference environment to the dimensions of the virtual object displayed in the augmented reality space. More specifically, the scale adjustment coefficient is a proportionality coefficient. For example, if the scale adjustment coefficient is 2, it characterizes that the dimensions of the virtual object in the reference environment are scaled up to 2 times to acquire the dimensions of the virtual object displayed in the augmented reality space. If the scale adjustment coefficient is 0.4, it characterizes that the dimensions of the virtual object in the reference environment are scaled down to 0.4 times to acquire the dimensions of the virtual object displayed in the augmented reality space. As a matter of course, it may be understood that the scale adjustment coefficient may also be a progression or matrix for characterizing proportional relationships between the virtual object in the reference environment and the virtual object in the augmented reality space in a plurality of dimensions. For example, the scale adjustment coefficient is {0.8, 1.5, 1.2}, characterizing that the dimensions of the virtual object in the reference environment are scaled down to 0.8 times in length dimension, scaled up to 1.5 times in width dimension and scaled up to 1.2 times in height dimension to acquire the dimensions of the virtual object displayed in the augmented reality space. Here, the specific implementation of the scale adjustment coefficient is not limited.

Further, exemplarily, an approach of determining the scale adjustment coefficient may include: determining the scale adjustment coefficient according to the proportional relationship(s) between the reference environment scale information and the scene scale information in one or more dimensions. The reference environment scale information is used for characterizing the dimension information of the reference environment. Reference is then made to FIG. 7A and FIG. 7B. FIG. 7A is a schematic diagram illustrating a reference environment according to embodiments of the present disclosure. In a possible implementation, the reference environment is a cuboid model surrounding the virtual object. The reference environment scale information is, for example, a length of the clinodiagonal of the cuboid model or the volume of the cuboid model. FIG. 7B is a schematic diagram illustrating another reference environment according to embodiments of the present disclosure. In a possible implementation, the reference environment is a rectangular box surrounding the projection of the virtual object. The reference environment scale information is, for example, a side or a diagonal of the rectangular box.

FIG. 8 . is a schematic diagram of determining a scale adjustment coefficient according to embodiments of the present disclosure. Referring to FIG. 8 , taking the diagonal length of the rectangular box being the reference environment scale information d1 as an example, exemplarily, the reference environment scale information d1 is equal to 1.25, and the scene scale information d2 of the real-world environment is equal to 2.5. Thus, it may be determined that the scale adjustment coefficient coef0 of the virtual object is equal to 2 according to the proportional relationship between the reference environment scale information d1 and the scene scale information d2 of the real-world environment represented by the augmented reality space.

Alternatively, the reference environment scale information may also be a sequence or matrix composed of a plurality of dimensions. In a possible implementation, the reference environment scale information is, for example, the size of the cuboid model shown in FIG. 7 in the dimensions of length, width and height. Alternatively, the reference environment scale information is, for example, the size of the rectangular box shown in FIG. 8 in the dimensions of length and width.

Correspondingly, the scene scale information is used for characterizing the dimension information of the real-world environment. Exemplarily, the implementation of the scene scale information corresponds to the implementation of the reference environment scale information. For example, if the real-world environment is a cuboid model or a rectangular box characterizing the environment where the first terminal device is placed, the scene scale information may be the clinodiagonal length or the volume of the cuboid model. Alternatively, the scene scale information may be a side or a diagonal of the rectangular box. The scale adjustment coefficient may be determined through the proportional relationship between the reference environment scale information and the scene scale information in a corresponding dimension. The scale adjustment coefficient may also be a sequence or matrix composed of a plurality of coefficients. If the scale adjustment coefficient is a sequence or matrix composed of a plurality of coefficients, the scale adjustment coefficient is determined by the proportional relationships between the reference environment scale information and the scene scale information in a plurality of corresponding dimensions, which will not be described redundantly.

S203: determining the display scale information according to the scale adjustment coefficient and the reference object scale information.

Exemplarily, the reference object scale information is used for characterizing the reference dimension information of the virtual object in the reference environment. Referring to FIG. 4 , the virtual football in FIG. 4 has a diameter of 0.3 m, which is the reference object dimension information. As a matter of course, it may be understood that the reference object dimension information may also be implemented by the volume and one or more dimensions, etc. of the virtual object, and the reference object dimension information may be set as needed, which will not be described here one by one redundantly.

Further, the reference object scale information is adjusted according to the scale adjustment coefficient making the reference object scale information scaled up or scaled down in one or more dimensions to acquire the display scale information. It needs to be noted that the reference object dimension information may be a sequence or matrix composed of a plurality of dimension values to characterize the dimension information of a plurality of dimensions of the virtual object in the reference environment. In a possible implementation, if the scale adjustment coefficient is a sequence or matrix composed of a plurality of coefficients, which correspond to a plurality of dimensions of the virtual object, corresponding weighting adjustment may be performed on a plurality of dimension values in the reference object dimension information according to the scale adjustment coefficient so that a plurality of dimensions of the virtual object may be adjusted according to different proportionality coefficients, allowing the display scale information of the virtual object to match the real-world environment in a plurality of dimensions.

In this embodiment, by setting a multi-dimensional scale adjustment coefficient and a multi-dimensional reference object scale information, the virtual object may be adjusted in a plurality of dimensions, so that the degree, to which the acquired display scale information in the augmented reality space matches the real-world environment in a plurality of dimensions, is increased, and the visual display effect is optimized.

In a possible implementation, the reference object scale information includes reference contour scale information of the virtual object and reference motion scale information of the virtual object, and the display scale information includes display contour scale information and display motion scale information. As shown in FIG. 9 , S203 includes two specific implementation steps S2031 and S2032.

S2031, determining the display contour scale information corresponding to the reference contour scale information of the virtual object according to the scale adjustment coefficient.

Exemplarily, the reference contour scale information is information for characterizing the contour dimension of the virtual object in the reference environment. For example, if the virtual object is a virtual football, its corresponding contour dimension may be any one of the diameter, radius, projected area and volume of the virtual football. The reference contour scale information is a parameter and corresponding value characterizing the diameter, radius, projected area or volume of the virtual football. For example, the reference contour scale information may be: the virtual football with a diameter equal to 0.6 m or a projected area equal to 0.28 m² or the like.

S2032, determining the display motion scale information corresponding to the reference motion scale information of the virtual object according to the scale adjustment coefficient.

In a possible implementation, the virtual object in the reference environment is dynamic, and therefore, the corresponding virtual object in the augmented reality space is also dynamic. For example, the virtual object may move from one position to another position according to a user instruction or a preset rule. The process is the motion process of the virtual object, and the information, which describes a moving distance of the virtual object in the motion process in the reference environment, is the reference motion scale information.

FIG. 10 is a schematic diagram illustrating a motion process of a virtual object according to embodiments of the present disclosure. Referring to FIG. 10 , the virtual object may move in the reference environment according to a user instruction or a preset rule. When the virtual object moves in the augmented reality space, in order to guarantee that a moving distance matches the real-world environment represented by the augmented reality space, the moving distance of the virtual object needs to be adjusted according to the scale adjustment coefficient, and the display motion scale information matching the real-world environment is generated. Specifically, as shown in FIG. 10 , if the virtual object is a virtual football and the moving distance (i.e., the reference motion scale information) of the virtual football in the reference environment is 0.5 m, the moving distance (i.e., the display motion scale information) of the virtual football in the augmented reality space is determined to be 1 m according to the scale adjustment coefficient coef1=2.

It needs to be noted that when the scale adjustment coefficient is a sequence or matrix composed of a plurality of coefficients, the reference motion scale information of the virtual object may be adjusted in a plurality of dimensions according to the scale adjustment coefficient. FIG. 11 is a schematic diagram of determining a moving distance of a virtual object with a scale adjustment coefficient according to embodiments of the present disclosure. Referring to FIG. 11 , the reference motion scale information of the virtual object in the reference environment is dis_1={1,1}, indicating that the virtual object moves from the origin {0,0} to position {1,1}. The scale adjustment coefficient coef2 is {2,1.5}. The reference motion scale information of the virtual object is adjusted according to the scale adjustment coefficient, causing the moving distances of the virtual object in both dimensions of X and Y to change in different proportions, and the acquired display motion scale information dis_2 is {2,1.5}. That is, in the augmented reality space, the virtual object moves from the origin {0,0} to {2,1.5}. Thus, the adjustment of the moving distances of the virtual object in different dimensions is realized.

Here, it needs to be noted that in a possible implementation, the technical solutions corresponding to steps S2031 and S2032 may be carried out together. That is, the reference contour scale information and the reference motion scale information of the virtual object are adjusted simultaneously according to the scale adjustment coefficient to generate the display contour scale information and the display motion scale information. In another possible implementation, the technical solutions corresponding to steps S2031 and S2032 may be carried out separately. That is, only the reference contour scale information or the reference motion scale information of the virtual object is adjusted according to the scale adjustment coefficient to generate the display contour scale information or the display motion scale information, correspondingly, and the unadjusted reference contour scale information or reference motion scale information is directly processed as the display contour scale information or the display motion scale information. This is not specifically limited here.

S204: displaying the virtual object in the augmented reality space of the first client according to the display scale information.

In this embodiment, steps S201 and S204 are implemented in the same way as steps S101 and S103 in the embodiment described above, which may be referred to the discussions of steps S101 and S103 for details and will not be described here redundantly.

FIG. 12 is a third flowchart of a method for augmented reality interactive display according to embodiments of the present disclosure. In this embodiment of the present disclosure, a step of receiving and sending the reference scale information is added on the basis of the embodiment shown in FIG. 6 . The method for augmented reality interactive display provided in this embodiment may be applied to a multi-user interaction scene to realize the multi-user interaction function based on AR among a plurality of users. Referring to FIG. 12 , this embodiment involves the following steps.

S300: receiving the reference scale information, in which the reference scale information includes reference object scale information, and the reference object scale information is determined according to a first interactive instruction acting on at least one second client.

In a possible implementation, the first client communicates with a corresponding server-side and receives the reference scale information sent from the server-side. More specifically, the reference scale information is included in a communication message sent from the server-side to the first client, and the first client acquires the reference scale information by receiving the communication message sent from the server-side.

Further, the reference scale information includes the reference object scale information used for characterizing the scale information of the virtual object in the reference environment. The reference object scale information is determined by the second client running on the second terminal device according to the first interactive instruction acting on the second client, and then the reference object scale information is sent to the server-side. Exemplarily, the second client runs on the second terminal device, and a user inputs the first interactive instruction to the second client through the human-machine interaction interface of the second terminal device to cause a change in the reference object scale information in the second client, for example, to cause a change in the contour dimension of the virtual object and/or to cause the virtual object to move. Specifically, for example, by swiping or tapping on the screen, the virtual object in the augmented reality space of the second client is controlled to change in contour dimension or to move. More specifically, the first interactive instruction is in a preset operation mapping relationship with the reference object scale information. For example, an operation instruction of tapping on the screen at a preset position may change the reference contour dimension information in the reference object scale information of the virtual object; an operation instruction of swiping the screen at a preset position may change the reference motion dimension information in the reference object scale information of the virtual object. When the reference object scale information of the virtual object changes, the display object dimension information of the virtual object also changes synchronously accordingly, i.e., the display image of the virtual object in the augmented reality space changes. The second client then communicates with the server-side and sends the reference object scale information to the server-side through the communication message.

S301: acquiring the scene scale information, in which the scene scale information is used for characterizing the dimension information of the real-world environment represented by the augmented reality space of the first client.

S302: determining the scale adjustment coefficient according to the relationship between the reference environment scale information and the scene scale information.

S303: determining the display scale information according to the scale adjustment coefficient and the reference object scale information.

S304: displaying the virtual object in the augmented reality space of the first client according to the display scale information.

The implementation and corresponding beneficial effects of steps S301-S304 in this embodiment of the present disclosure are similar to those of steps S201-S204 in the embodiment shown in FIG. 6 , which may be referred to the descriptions in the embodiment shown in FIG. 6 for details and will not be described here redundantly.

S305: receiving a second interactive instruction, and adjusting the reference object scale information in the reference scale information according to the second interactive instruction.

Exemplarily, the second interactive instruction is instruction information input by a user through the human-machine interaction interface of the first terminal device to the first client, in which the second interactive instruction is implemented in the same way as the first interactive instruction. Specifically, for example, by swiping or tapping on the screen, the virtual object in the augmented reality space of the first client is controlled to change in contour dimension or to move. More specifically, the second interactive instruction is in a preset operation mapping relationship with the reference object scale information. For example, an operation instruction of tapping on the screen at a preset position may change the reference contour dimension information in the reference object scale information of the virtual object; an operation instruction of swiping the screen at a preset position may change the reference motion dimension information in the reference object scale information of the virtual object. When the reference object scale information of the virtual object changes, the display object dimension information of the virtual object also changes synchronously accordingly, i.e., the display image of the virtual object in the augmented reality space changes. The first client adjusts the reference object scale information in the reference scale information according to the received second interactive instruction and the preset operation mapping relationship.

It needs to be noted that after the reference object scale information in the reference scale information is changed, the display object dimension information corresponding to the virtual object may also change synchronously. The first terminal device may continue to perform the steps in the embodiment shown in FIG. 3 or FIG. 6 to display the virtual object with the changed reference object scale information in the augmented reality space of the first client.

Exemplarily, step S305 may be performed together with other steps in this embodiment or may be performed independently of other steps in this embodiment, which will not be limited here.

S306: sending the reference scale information to the second client.

Specifically, to realize interaction among a plurality of clients, the first client sends the reference scale information generated according to the second interactive instruction to the second client, allowing the second client to display the virtual object with the corresponding contour dimension and moving distance in the augmented reality space according to the reference scale information, and thus realizing the interaction between the first client and the second client.

FIG. 13 is a schematic diagram of realizing multi-user interaction by adjusting a virtual object with an interactive instruction according to embodiments of the present disclosure. Referring to FIG. 13 , the first terminal device is a smart phone, and a user swipes the screen on the smart phone to adjust the reference object scale information in the reference scale information, causing the virtual football in the augmented reality space of the first client to move a corresponding distance. Meanwhile, by sending the reference scale information to the second terminal device, the virtual football in the augmented reality space of the second client also move a corresponding distance that matches the real-world environment where the second terminal device is placed.

To better illustrate the implementation process of the method for augmented reality interactive display provided in this embodiment, the following description is made below by taking a more specific embodiment as an example.

FIG. 14 is a chart of interactive signaling in a method for augmented reality interactive display according to embodiments of the present disclosure. Referring to FIG. 14 , a first client runs on a first terminal device, while a second client runs on a second terminal device. Exemplarily, the first client and the second client may be the same application client based on AR, for example, an AR game client. The first client and the second client communicate with a server-side, and the server-side provides services such as information processing and message forwarding for the first client and the second client so that information interaction may be realized between the first client and the second client. The server-side runs on a server, and the first terminal device and the second terminal device are in communication connection with the server via a network, respectively. This embodiment involves steps as follows:

S401, the server establishes the communication connection of the first terminal device with the second terminal device.

S402, the first terminal device acquires scene scale information and preset reference scale information, in which the reference scale information includes reference environment scale information and reference object scale information.

S403, the first terminal device determines a scale adjustment coefficient according to a relationship between the reference environment scale information and the scene scale information.

S404, the first terminal device determines display scale information according to the scale adjustment coefficient and the reference object scale information.

S405, the first terminal device displays a virtual object in the augmented reality space of the first client according to the display scale information.

S406, the first terminal device receives a swiping instruction input from a user and adjusts the reference motion scale information in the reference object scale information of the virtual object according to the swiping instruction.

S407, the first terminal device redetermines the display scale information according to the reference object scale information and displays the virtual object according to the display scale information.

S408, the first terminal device sends the reference scale information, which includes the reference object scale information, to the server.

S409, the server forwards the reference scale information to at least one second terminal device.

S410, the second terminal device acquires scene scale information and the reference scale information, in which the reference scale information includes the reference environment scale information and the reference object scale information.

S411, the second terminal device determines a scale adjustment coefficient according to a relationship between the reference environment scale information and the scene scale information.

S412, the second terminal device determines display scale information according to the scale adjustment coefficient and the reference object scale information.

S413, the second terminal device displays a virtual object in the augmented reality space of the first client according to the display scale information.

S414: the second terminal device receives a tapping instruction input from a user and adjusts the reference contour scale information in the reference object scale information of the virtual object according to the tapping instruction.

S415, the second terminal device redetermines the display scale information according to the reference object scale information and displays the virtual object according to the display scale information.

S416, the second terminal device sends the reference scale information, which includes the reference object scale information, to the server.

S417, the server forwards the reference scale information to at least one first terminal device.

In this embodiment of the present disclosure, by synchronizing the reference object scale information among a plurality of terminal devices, dynamic interaction based on AR among the plurality of terminal devices may be realized. Meanwhile, the plurality of terminal devices perform weighted adjustment and display on the reference object scale information according to the scene scale information corresponding to the environment in which they are located, so that the virtual object in the augmented reality space may match different environment dimensions. With reference to the embodiment shown in FIG. 13 , when a user inputs the swiping instruction to the first terminal device, the virtual football in the augmented reality space of the first client moves, for example, 0.5 m. The first client then synchronizes the reference dimension information corresponding to the virtual football to the second client of the second terminal device via the server. The second client perform weighted adjustment and display on the reference object scale information in the reference dimension information according to the scene scale information, causing the virtual football to move, for example, 3 m in the augmented display space of the second client. Thus, the moving distance of the small ball better matches the real-world environment displayed by the second client, thereby improving the visual effect of the virtual object and enhancing the experience of user interaction.
